Synopsis

Ealing’s defining contribution to the police procedural genre – with ex-policeman TEB Clarke’s script lending authenticity – sits on the border between the studio’s dark and light sides. There’s tragedy at its core, and a portrait of snarling, lawless youth (a mesmerising young Dirk Bogarde) that’s tough for its time, not least for Ealing. But if it takes us to dark places, its conclusion expresses an irrepressibly optimistic and comforting vision of the ability of society to overcome its most hostile elements.
